CAFE based Multi-scale Modelling of Ductile-to-Brittle Transition of Steel with a Temperature Dependent Effective Surface Energy
(Journal article; Peer reviewed, 2019)It is still a challenge to numerically achieve the interactive competition between ductile damage and brittle fracture in ductile-to-brittle transition (DBT) region. In addition, since two types of fracture occur at two ... -
Effect of heat input on nanomechanical properties of wire-arc additive manufactured Al 4047 alloys
(Peer reviewed; Journal article, 2022)Heat input is one of the most important process parameters during additive manufacturing (AM). It is of great significance to understand the effect of heat input on the microstructure and nanomechanical properties, as well ... -
Effects of constituent particle content on ductile fracture in isotropic and anisotropic 6000-series aluminium alloys
(Peer reviewed; Journal article, 2021)Tension tests on smooth and notched specimens were conducted for four 6000-series aluminium alloys to assess the effects of constituent particles on ductile fracture at different stress states. Two of the alloys are ... -
Effects of heat-treatment on the plastic anisotropy of extruded aluminium alloy AA6063
(Journal article, 2017)The plastic anisotropy of aluminium alloys is known to depend not only on the crystallographic texture but also on the heat-treatment, and this effect has been studied on various alloys both experimentally and numerically. ... -
Effects of local grain size and inclusions on the low-temperature toughness of low-carbon as-quenched martensite
(Journal article; Peer reviewed, 2018)The segregation of alloying elements that occurs during the solidification of steel leads to microscale and macroscale microstructural heterogeneity that can cause anomalous mechanical behaviour. The centreline macrosegregation ... -
Experimental and numerical study on hydrogen-induced failure of X65 pipeline steel
(Peer reviewed; Journal article, 2024)Hydrogen-induced fracture of X65 pipeline steel under in-situ electrochemical charging is investigated by using in situ slow strain-rate tensile (SSRT) test, hydrogen diffusion test, fractography analysis, and finite element ... -
A framework for predicting the local stress-strain behaviors of additively manufactured multiphase alloys in the sequential layers
(Peer reviewed; Journal article, 2022)The additive manufacturing (AM) process often results in non-uniform microstructure and different mechanical properties in sequential layers, impacting the overall performance of the AM-ed component. However, it is extremely ... -
Influence of constituent particles on fracture of aluminum alloys under high-triaxiality loading
(Peer reviewed; Journal article, 2023)Single-edge notch bending tests are conducted to study the influence of constituent particles on the fracture resistance of aluminum alloys 6061, 6063, and 6110 under high-constraint loading conditions. The alloys are ... -
Influence of particle content on the ductility of extruded non-recrystallized aluminium alloys subjected to shear loading
(Peer reviewed; Journal article, 2022)In-plane shear tests were conducted on two extruded 6000-series aluminium alloys to investigate the influence of constituent particles on ductile fracture. The two alloys have previously been characterized and found to ... -
